Tunisians protest a ban on protests

Tunisian police used tear gas to break up a rally in Tunis's symbolic Avenue Bourguiba, on Monday commemorating "Martyr's Day". Protests in central areas of the capital have been banned since last month, but that hasn't stopped demonstrators angry with the ruling moderate Islamist Ennahdha party from turning out in the streets. It comes at a time of increasing pressure on the embattled coalition government from both ends of the political spectrum.
